CH<x>:IMPedance
Sets or queries the impedance setting at the specified input channel. This is
equivalent to setting Impedance in the Ch<x> Coupling Impedance side menu.
TDS 500B, 600B and 700A: When you attach an active 50 probe to an input
channel of the TDS 500B, 600B or 700A, the oscilloscope reduces the maximum
vertical scale from 10 V to 1 V per division. For example, an active 10X probe
would provide 10 V per division and a passive 10X probe would provide 100 V
per division.

CH<x>:COUPling
sets the specified channel to 50 impedance.
sets the specified channel to 1 M impedance.
establishes 50 impedance on channel 1.
might return , indicating that channel 3 is set to 1 M impedance.
CH<x>:OFFSet
Sets or queries the offset, in volts, that is subtracted from the specified input
channel before it is acquired. The greater the offset, the lower on the display the
waveform appears. This is equivalent to setting Offset in the Vertical menu.
